About this compound
Oxytocin
Neurohypophysial nonapeptide
First disclosed
1953
Oxytocin is a nine-amino-acid neurohypophysial peptide that acts on the oxytocin receptor — one of the first peptides ever chemically synthesised. It remains a standard reference ligand in neuroendocrine and receptor-signalling research.
Oxytocin-receptor agonism is studied in vitro for neuroendocrine signal-transduction pathways.

Oxytocin is the endogenous nonapeptide hormone oxytocin, supplied by MyPeptides for laboratory research use only.
Oxytocin is the endogenous nonapeptide hormone oxytocin. MyPeptides supplies it as a lyophilised 2 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Oxytocin in social-behaviour and endocrine research models. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Oxytocin order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. Disulphide-bridged nonapeptide — supplied lyophilised so the bridge stays intact.
